This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "OpenBTS' transceiver retro-fit".

The branch, master has been updated

This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (68475102023be985d45698acb81b888f78db8728)
            \
             N -- N -- N (2c650a6895f573e4455f55f0d1ed136ba8ae4744)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

commit 2c650a6895f573e4455f55f0d1ed136ba8ae4744

    common: Add mandatory length field to UDP receive calls
    
    Current UDP receive reads up to MAX_UDP_LENGTH bytes into the
    passed in buffer, which may lead to buffer overflow if the
    write buffer is of insufficient size.
    
    Add mandatory length argument to UDP socket receive calls.

commit d4555f267e284d14e9e877f8f82da8bcc2d76d7a

    common: Restrict UDP binding to localhost only
    
    Reported security vulnerability where control and data UDP
    packets can be injected into the transceiver externally due
    to socket binding to all interfaces using INADDR_ANY.
    
    Existing socket interface does not allow specifying local
    address; only the local port and remote address/port are
    arguments.
    
    Restrict socket bind to localhost with INADDR_LOOPBACK. If
    external interfaces do need to be used, the API should be
    modified to allow specifying the local socket address.
